Linrad Compilation notes

 Offf it's horrible. Developer doesn't believe in writing good instructions.

sudo apt-get install libx11-dev libportaudio2 subversion libftdi-dev libusb-1.0-0-dev


sudo ln -s /usr/lib/x86_64-linux-gnu/libportaudio.so.2.0.0 /usr/lib/x86_64-linux-
gnu/libportaudio.so


# FUCKING SUBVERSION!!! IN 2023!!!
svn checkout https://svn.code.sf.net/p/linrad/code/trunk linrada


./configure --with-help


./configure --with-x11-64 --with-portaudio-64 --with-libftdi-64 --with-soft66-64 --with-rtlsdr-64


make xlinrad64


Then use https://qsl.net/ve7vv/Files/Linrad_installation_Guide.pdf
to understand how to set up the software.

Even after this, just delete the whole thing and install SDR++.

Kubuntu and USB audio devices

I've been setting up remote stations using USB devices but fucking Pulse Audio won't detect them correctly.

First, wipe out your pulse configuration files in .config/pulsle and volume/.config/pulse

Then edit /etc/pulse/default.pa and add the following lines, hw:1,0 is my USB card. You can see this using aplay -l

load-module module-alsa-source device=hw:1,0
.ifexists module-udev-detect.so

Reboot and have fun.

Kubuntu and VNC as a service

I've been setting up an old laptop so that I can use it with my new radio as a remote station.

Latest Kubuntu uses fucking useless Wayland so VNC doesn't work well. TightVNC fails to start up anything useful so forcing X11 is a necessity.

This is a good solution. Found it on Reddit.# install x11vnc

sudo apt install x11vnc

# set a VNC password. VNC security is lacking, so this is optional.

sudo x11vnc -storepasswd /etc/x11vnc.passwd

# follow the prompts to create a password and then lock down the password file.

sudo chmod 0400 /etc/x11vnc.passwd

# would be nice if there was an service created for x11vnc, but there isn't so create one.

sudo nano /etc/systemd/system/x11vnc.service

# paste the following text block into into /etc/systemd/system/x11vnc.service

# If you are NOT using a password, then remove this section: -rfbauth /etc/x11vnc.passwd

[Unit]
Description=Start x11vnc
After=multi-user.target display-manager.service

[Service]
Type=simple

ExecStart=/bin/sh -c '/usr/bin/x11vnc -display :0 -forever  -rfbport 5900 -xkb -noxrecord -noxfixes -noxdamage -nomodtweak -repeat -shared -norc -auth /var/run/sddm/* -rfbauth /etc/x11vnc.passwd'

# For KDE ONLY, include the "Restart" and "RestartSec" commands, otherwise you could just use "-loop" but that is busted since at least kubuntu 18.04
# This was added because logging out killed the x11vnc session even though "-loop -forever" was enabled.
# NOTE: In order to use this, make sure "-loop" switch is not used above!!
# NOTE: While vnc client will disconnect, at least the vncserver will restart itself to client can connect again.
Restart=always
RestartSec=1

ExecStop=/usr/bin/killall x11vnc

[Install]
WantedBy=multi-user.target

# reload systemd with the brand new x11vnc service file

sudo systemctl daemon-reload

# start x11vnc service so you can use it now

sudo systemctl start x11vnc

# enable x11vnc to start at boot so you can use it later

sudo systemctl enable x11vnc

Master Boot Record

Once in a while you encounter something so delicious & beautiful, it makes your life significantly better.

Master Boot Record is such a thing. I am addicted. Especially his masterpiece Interrupt Request is now a regular occurrence in my playlist because it's simply awesome.

From power-metal to symphonic-metal, and a lot of trash thrown into it, we're told it's all done in a 486DX machine with 64GB of RAM, and a sequencer software. It's very MIDI, but in a good way.

I have listened to various chiptunes in the past, but apparently this is called Dark Synth Wave. Some also call it synth-metal. I have my own name for it, fucking awesome music. As far as I'm concerned, no other categorizations are necessary.

You can get the whole discography for peanuts from Bandcamp, and I'd definitely recommend Internet Protocol and Interrupt Request, but there are too many favourites to select from. Do your own thing, and this chap definitely does that.

Not only the music is great, the fan experience is awesome. The albums come with cryptic puzzles you have to solve, the last album came out with an IRC channel & a telnet-enabled BBS with ANSI support where you can get hints for the puzzle, and this unlocks extra songs. Overall the enjoyment factor goes to 11 with Master Boot Record, you don't get a half-arsed CD print.

Oh yeah, if you're inclined to do so, you can actually get the albums on cassette player! Full retrograde orbit achieved! Also you can get them on floppy disc as well, 5.25" style - half the kids in the office don't even know what a floppy disk is...

This is a great time for us, the music, the media, the internet empires, they're all built by us geeks, for us geeks. Shame about Facebook and no-longer "do-no-evil" Google, but hey, there's still good music to head bang to.

Did I mention, you can get pretty much all Master Boot Record songs on his YouTube channel. What not to like about this guy...

SQL Developer in Windows and the wrong type of JDK

I don't want yet another JDK installed, also I don't want to use Oracle JDK any more.

I'm slave to a Windows laptop at work, and SQL Developer is a shitshow.

If you enter the wrong JDK, for example OpenJDK's J9 engine, then the piece of crap doesn't work.

There's a SQLDeveloper.conf inside the SQL Developer installation, with a SetJavaHome variable, but no, it's not that one. That'd be TOO easy. Instead, you got to locate which file it had last modified in your user folder, and that'll be in product.conf inside AppData\Roaming\sqldeveloper\{version}.

There, you can point ot to your Favorite JDK...

SetJavaHome C:\Java\OpenJDK8U-jdk_x64_windows_hotspot_8u181b13\jdk8u181-b13

TortoiseGit loses its overlay icons...

Windows suck.

Run Regedit.

Open
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\ShellIconOverlayIdentifiers

Locate Tortoise entries.

Make sure they are at the top of the sort list, if necessary add things like "   1" to the name. F5 to refresh.

Kill all running Explorer processes, rerun a new Explorer process from Task Manager, if necessary. If you are too scared, simply relogin.

What happens is, OneDrive POS interferes with the Tortoise shell icon overlay extension. Mikisoft has become cleverer and does the same kind of trick in the ordering with spaces in the One Drive names. Simply sorting Tortoise names earlier than One Drive icons solves the issue.

Centos 7 Firewall

Sigh... Don't do this at home...

  130  systemctl disable firewalld
  131  systemctl stop firewalld

SystemD must die die die - firewallD

Sigh... More here.

firewall-cmd --reload

VirtualBox 5 and still not working

VirtuaBox is gone to version 5 and it's VMDK support is still crap.

It's my mistake, when I was creating the last VM I should have paid attention, I was sleepcreatingVMs and accidentally created the VM with a VMDK disk. WRONNNGGG!!! I needed an other 100G on the VM, and then I started banging my head on my desk again.

Luckily it's just tedious stuff. Our good friend qemu-utils package comes to our rescue again, so it's just a waste of space and time. We got to convert it to a better supported format, and then do the work:

time qemu-img convert -f vmdk -O vdi /fullpathtodisk.vmdk  /fullpathtodisk.vdi
VBoxManage modifymedium disk /fullpathtodisk.vdi --resize 200000 

Note that you got to count the zeros correctly. I typed 20000 and it gave me the unhelpful message:  

0%... 
Progress state: VBOX_E_NOT_SUPPORTED 
VBoxManage: error: Resize medium operation for this format is not implemented yet! 

Well, yes, resizing to smaller sizes is not implemented, but at least be more helpful to a sleep-reprived sysadmin. I was telling it to resize it to 20GB, not 200GB! I scratched my head, googled the error, had some coffee, thought about it for a while, came back, tried the vmdk again, wasted more time, only after that I counted the zeros and cursed at myself loudly.

It would be nice if VirtualBox, after all these years, would support mnemonics like MB, GB... 

Syntax error: --resize: RTGetOpt: Command line option has argument with bad format. 

Darnit!!!

Embrace the dark side:SELinux

It's annoying.
It works.

If you've got a home directory somewhere else than /home, you might have some funny business. It usually shows up as "/usr/bin/xauth: timeout in locking authority file .Xauthority". Some other security related things stop working too.

This is how all that goes away.

Edit /etc/selinux/semanage.conf
usepassword=True
yum install policycoreutils-python

Clone the context from the standard home directory layout into the new home directory, my users are under /test, i.e., /test/user
semanage fcontext -a -e /home /test
restorecon -R /test

Job done, everything works as intended.

VirtualBox & VERR_NOT_SUPPORTER with VMDK

So, you've got your 2GB-split VMDK and you want to import to your local Virtualbox and it's not working at all:

hakan@hakan-laptop:16:29:36:~/snafu$ VBoxManage showhdinfo demo.vmdk

VBoxManage: error: Could not get the storage format of the medium '/home/hakan/snafu/demo.vmdk' (VERR_NOT_SUPPORTED)
VBoxManage: error: Details: code VBOX_E_IPRT_ERROR (0x80bb0005), component Medium, interface IMedium, callee nsISupports

The version of Virtualbox on Ubuntu 15.04 is not capable of handling this format at the moment. Install Qemu-tools and do the conversion there and stop wasting time:

time qemu-img convert -f vmdk -O vdi demo.vmdk demo.vdi 

Now that's better:

hakan@hakan-laptop:16:37:34:~/snafu$ VBoxManage  showhdinfo demo.vdi

LoadRunner, SSH and Remote Agents

I'm running LoadRunner 11.52, RTE with SSH and some remote agent servers to run the load.

And it won't work. The scripts work fine with Vugen but won't work with the Controller.

The reason is this:

[HKEY_CURRENT_USER\Software\Ericom Software\SSH\SshHostKeys]
"rsa2@22:blablabla"="0x25,randomstringforsshkey"

This little piece of crap needs to be in the registry before Ericom - which LoadRunner uses for your SSH connection can connect. It doesn't use Plink, it doesn't use any clever stuff. And if you're using a remote agent with a local system account, whatever I tried - IT DOES NOT WORK!

There are people who claim if you convert this into a HKEY_LOCAL_MACHINE registry entry, it should work, it did not in my case.

In the end I threw up the towel, asked the LR agent to be run as a named user, ran the script ONCE with that user using Vugen - this loaded the key into the registry - and then everything worked from the Controller.

The key is loaded to the registry when you connect to it first time - it pops up a window and asks if you are happy with the fingerprint and want to save it - which you answer by clicking to the "YESSSS" button", unless you're an idiot.

Guess what. LoadRunner is not clever enough to auto-accept this key if you are running this inside the controller. It still prompts for it. You just never see the prompt. It's hanging there, in the ether, waiting for a ghost to find it and try to touch with its cotton rags and see if it can activate the YESSSSSSSS button, forever....

Of course, this is very annoying. For every different server and every different controller you want to use, you have to go through this.

You can have short-cuts. You can do it in one server, then save the registry keys and import into the servers but still, you got to use a named user, just don't bother with the local system account, it's just not worth the stress it's going to cause you.

Probably will apply to 12 as well. 

Why you shouldn't hate and disable NetworkManager anymore

James Hogarth has posted a nice mail to the CentOS mailing list on why we shouldn't hate NetworkManager anymore and linked to a very good article on the nmcli. One should bookmark this for future reference.

I used to loathe things that make life easy by trying to "wrap things up" since they make edge cases significantly harder to resolve (and what I mean by edge cases is, servers) but I give up. Life is too short arguing about such things on and on. Eventually things get resolved and people move on I guess and I got to accept NetworkManager instead of fighting against it doing stupid things against my will. Hopefully enough things have been fixed so that it's now sane enough.

I am still against distributions doing "their own things" on such fundamental levels, I accept that I do not matter in the big scheme of things.

IMHO, such basic operations like networking should be standardized across platforms so that we can achieve such operations w/o worrying about such stupid things. I should expect to have certain things always in my service...

Oh well..

LoadRunner 11.52 and weird compilation issues

I've had a perfectly working LoadRunner Java over HTTP script for ages. This stopped working once it was tried on 11.50 and 11.52.

It "compiles" inside the VUGen but fails to run inside VUGen or Controller and produces the following error:

After raising a call with HP, their suggestion was to move all of the <Vector> and List declarations to global sections, not inside methods.

Like this:
@@ -436,14 +437,27 @@ public class Actions {
         *
         * @return
         * @throws Throwable
-        */
+       */             
+      
+       Vector<Vector<String>> pterryPack = null;
+        Vector<Vector<String>> ankhmorphocContents;
+        //Vector<String> vetrinari_results;
+        Vector<String> fubarDetails;

+        Vector<String> rincewindConfig;
+        Vector<Vector<String>> ConanDetails;
+        Vector<Vector<String>> unseenuniversityDetails;
+        Vector<Vector<String>> discworldData;

OK, in many ways my Vector etc. declarations are a bit funny wrt to the modern Java coding standards but it is the way the legacy code I work with is written so I shouldn't get the flack. The funny thing is it works with Java 1.6 and LoadRunner 11.0 but not 11.52, it -looks- like a classpath issue based on various discussions on the net but it isn't. It looks like the parser LoadRunner uses to create the runtime classes for data injection can't handle such Vector and List declarations (legitimately) peppered around the code and must observe them up front and prepare itself.

Beware.

Good riddance

Ubuntu One is no more. Long live the new king, OwnCloud version 6. Don't use v5. It shreads files for fun.

Help! Git eats all of my memory!

My little server runs a whole a lot of things on 2GB RAM. Then I run git clone with some files as big as 1GB in the repository and the poor server keels over, sticks its legs out and starts pining for the fjords.

The following reduces the amount of memory & resources Git uses. I am obviously sure it will make it crappier, slower and make it run as slow as molasses but at least it won't kill the box. That's a win in my book. Consult the manual for further reading.

git config --global pack.windowMemory "100M"
git config --global pack.packSizeLimit "100M"
git config --global pack.threads "1"
